COMPRESSOR-PUMP FOR REFRIGERATI NG APPARATUSES.

EPECIPICATION forming part of Letters Patent No. 368,672, dated May 24.1887.

Application filed October 12. 1886. Serial X0. 216,022. (No model.)

To all whom it may concern:

Be it known that l, EDGAR PENNEY. a citizen of the United States,residing at Waynesborough, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inCompressor Pumps for Iiefrigerating-Machines; and I do hereby declarethe following to be a full, clear,- and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to vertical compressorpumps forrefrigeratingmachincs.

Vertical compressor pumps of this class have heretofore been difficultof construction, by reason of the fact that the column or main frame wasmade of a single casting which was so large that it requiredextraordinary facilities for molding, casting, and finishing the same. V

One of the objects of my invention is to provide such a construction ofthe main frame of this class of pumps as to enable them to beconstructed by the ordinary appliances of machine-shops and foundries,whereby the cost of the same is greatly cheapened.

My invention consists in the peculiarities of construction hereinafterdescribed, and particularly pointed out in the claims.

In the drawings, Figure 1 is an end elevation of a doublecompressor-pump embodying my improvements, partly in section. Fig. 2

is a plan of a single pump of the same charac-' ter. Fig. 3 is a plan ofa double compressorpump, partly in section. Fig. 4. is an elevation,with parts in section, on line a: m in Fig. 3.

The column or main frame of a single compressor-pump made in accordancewith my improvements is composed of two main parts, A A. These parts aremade larger at the base, as is usual in this form of devices, and areprovided with exterior base-flanges, a, which are provided with suitablebolt-holes. The bottoms of these parts are provided with dowels, whichengage suitable openings in the These parts are also bolted to suchgirders and to anchor-plates embedded in the masonry-support. At thebase the inner sides of these castings are provided with flanges F,having perpendicular faces f, and at the top they are provided withflanges F F, which are connected by a web having a single face, g, asshown in Fig. 4. Between the upper and lower ends the parts A A areprovided with guides H for the cross-head slide. The faces of g f andthe face of the slides are all in the same plane or a direct line witheach other. This construction permits the necessary planing of the partsA A to be done in a speedy and economical manner.

Between the flanges F of the parts A A are mounted the castings G,having bearing for the main operatingshaft, commonly calledpillow-blocks, and between the faces g, at the upperend of A A, ismounted the pump-cylinder base I. The castings G are centered for theshaft, and are then planed from a center line to leave the bearing forthe shaft exactly midway of the casting, so that these parts areinterchangeable and rcversi ble. The pump-base is finished in a likemanner. These parts are connected securely to the parts A A, with whichthey come in coir tact, by strong bolts uniting the parts A A into asingle frame or column.

The part A of the column is provided on its outer side with faces 6 c.To the lower of these faces is secured the engine-bed E, with across-head guide, e, cast or bolted to the same. The upper cross-headguide, 0, is attached to a separate' girder connected at one end withthe face 6 of the part A, and at the other end to the upper part of theengine-bed. The part A of the column is provided with the opening Kbetween the faces 6 e for the passage of a link or connecting rod fromthe crosshead of the main shaft. In case'of a. single pump this mainshaft is provided with a fly-wheel at one or both extremities outside ofthe pillowblocks, and is provided midway of its length with a crankreceiving the link or connectingrod of the pitman connecting with thecrosshead of the engine, and a pitman connects to a cross head mountedon the slides H H for operating the pump.

The end of the engine-bed E is centrally bored for the passage of thepiston, and the cylinder is bolted thereto in the usual manner. Thepassage-way for the piston in the enginebed, the guide thereon, and theguide on the IOC girder E are centrally disposed upon such parts, sothat there is no right or left hand to the engine construction.

WVhen a double pump is required such additional pump is supported on acolumn or frame of two main parts, B B, which are of the same form aspart A of the firstdescribed frame or column, except that instead ofhaving two flanges, F, one at each side of the base, they may have sucha flange at one side only. Between the flanges of the parts 13Bapillow-block of the character described is placed and securely boltedin position. The main shaft is in this instance extended and given abearing in such block, and it is provided with a crank in the center ofthe column or frame, as already described.

It is found that a single bearing or pillowblock is sufficientfor thisadditional pump; but if preferred the parts B B can be made exactly likethe part A, and two hearings or pillowblocks employed. The column orframe B B is attached to the foundation-girders A2111 the same way as AA, and it is anchored in the same manner. At the top the two columns areconnected by the rods D with the pipeferrules D, inclosing the samebetween the columns.

If desired, more pumps constructed as just described may be added to thestructure'.

It will be seen that by my construction the cumbersome parts of machinesof this class are made in such divisions that they can be more easilycast and finished and their cost greatly eheapened, while at the sametime provision is made for securing such parts readily and securelytogether, forming a structure which possesses the requisite strength towithstand all working strains.

The pillow blocks and pump bases being made in the manner described, itwill be seen that the parts are made in the most economical manner, andthat there can be no difficulty when putting the parts together insecuring the proper alignment.

It will also be seen that the pump, whether single or double, isreversible, and can be readily made a right orleft hand pump, asdesired.

1. In a compressor-pump, a column or frame consisting of two main partsand intermediate connecting parts, the attaching-faces at the top andbottom of the two main parts being atthe same verticalplane,substantially as described.

2. The combination, with the two main parts A A, having attachingfacesat the top and bottom in the same vertical plane, of pillowblock andpump-base, each centered and balanced, substantially as described.

3. A sectional standard of a com pressorpump frame or column formed withattachingfaces on one side, at the top and bottom, and between the two aguide the face of which and said attaching-faces are all in one plane,substantially as described.

4. The combination,with a compressor-pump frame, of an engine bedconnected thereto having 'a cross-head guide and a girder connecting theupper part of said engine bed with the pump-frame and provided with across-head guide opposite the guide upon the engine-bed, substantiallyas described.

5. The combination, with a co m pressor-pum p frame, of an engine-bedattached thereto, and provided with a cross-head guide and agirderconnecting the upper part of said bed, and the pump-frame also providedwith a cross-head guide, the said guides being centrallyloeated on saidparts, substantially as described.

In testimony whereof I affix my signature in p resenee of two witnesses.

EDGAR PENNEY.
